Hi Andrea,
did you look on the php error log file?

Hi Pietro,
1.I've tried to invoke mapserver in cgi mode and it seems ok.
http://webgis.provincia.biella.it/cgi-bin/mapserv?map=/opt/fgs/apps/mapservergeo/map/basewms.map&mode=map&layer=stati
2. We looked on the apache log file and we fixed some errors we had in
a php file.
Anyway things are not changed.

Please, do you have anything else to suggest?
Thank you very much for your help
ciao

Subject: Re: [mapserver-users] WMS problem
Hi Andrea,
1. no
2. no matters
3. It is difficult to answer...
If the problem is EXTENT & PROJECTION, remember that a .map file
has the PROJECTION set at map level and PROJECTIONs set at layers
level; the map Projection is the projection system of the result
of the map (i.e. the map image), the layer Projection is the
projection system of the data source of the layer. If a layer
datasource projection differs from the map projection, you must to
set it, otherwise ms try to project the data according with map
projection.
Try invoke mapserver in cgi mode to see the results:
http://the.host/cgi-bin/mapserv?map=/path/of/the.map&mode=map&layer=
...
Imho your problem isn't the map, but occurs in your php script.
Take a look on the php error log: it is a text file, its path is
set in your php.ini file (error_log directive, can be an absolute
or relative path)
4. obviously scale is nonsense when using non-projected reference
systems like epsg:4326, but mapserver does not know.

Hi, we have this system working with MapServer version 4.8.2, PHP version
4.4.2. I am trying to do a map that shows both layer (WGS84 shapefile) and
WMS data togheter. The starting response is ok, but I get the blank image
from the first pan or zoom on. This is the example URL:
http://webgis.provincia.biella.it/apps/maplab/projects/gmf_apps/basewms4/wmdmap.php
I guess the problem is due to wrong parameters for EXTENT, SIZE and
PROJECTION in the mapfile. These are: EXTENT -15 25 40 70 SIZE 470 520
PROJECTION "init=epsg:4326". The question are: 1. the SIZE (in pixel) has
to be proportional to the EXTENT? 2. if yes, how to obtain the right values
for the EXTENT? 3. if not, where is the problem? 4. in a map with geographic
non-projected data like this, is correct to have value for scale of the
representation since UNITS are DD? I would be very grateful for any help
from you all, thanks! Best regards andrea ardito P.S. If I set no layer in
the map file, and I try to represent only WMS layer (adding them from
"Servizi WMS" button), it works.
